Salafist threat growing, interior ministers say

German state interior ministers are warning of a rise in radical Salafist Islam that poses a risk of home-grown terrorism, with one politician calling for changes to residency laws so "hate preachers" can be more easily deported.

Hesse Interior Minister Boris Rhein of the conservative Christian Democratic Union told daily Die Welt that Salafism was a "centre and pivot for those who want to participate in so-called holy war."

"Salafism can in this way lay the path to Islamist terrorism," he said, adding that the law needed to be changed so that "hate preachers" can be more easily thrown out of the country.
